The Bank of Happinesssets itself apart because it doesn't involve money or credit. Founded five years ago in Tallinn, the capital of Estonia, it's actually a forum in which more than 2 000 civic-minded individuals from Estonia and other countries connect to offer or receive services free of charge.

Founder Airi Kivi says the goal is to make people think and act with their hearts.
